(Z)-3-(Anthracen-9-yl)-1-(2-eth-oxy-phen-yl)prop-2-en-1-one.

ABSTRACT: The mol-ecule of the title chalcone, C(25)H(20)O(2), consisting of 2-eth-oxy-phenyl and anthracene rings bridged by a prop-2-en-1-one unit, is twisted and exists in the Z configuration with respect to the central C=C bond. The dihedral angle between the benzene and anthracene rings is 78.17?(9)°. The propene unit makes dihedral angles of 44.5?(2) and 81.1?(2)° with the benzene and anthracene rings, respectively. The eth-oxy substituent is almost coplanar with the attached benzene ring [C-O-C-C torsion angle = 178.57?(19)°]. In the crystal, mol-ecules are linked into chains along the a axis by weak C-H?O inter-actions. The crystal structure is further stabilized by C-H?? inter-actions.

Project description:In the title compound, C(17)H(16)O(3), the carbonyl group is in an s-cis configuration with respect to the olefinic double bond. The dihedral angle between the two benzene rings is 2.85 (3)°. The prop-2-en-1-one bridge makes dihedral angles of 4.77 (4) and 4.15 (4)°, respectively, with the 2-hy-droxy-phenyl and 4-eth-oxy-phenyl rings. The eth-oxy group is coplanar with the attached phenyl ring [C(ar)-O-C-C = 179.72 (5)°]. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, mol-ecules are stacked in an anti-parallel manner to form columns along the b axis. The columnar structure is stabilized by C-H⋯π inter-actions involving the 2-hy-droxy-phenyl ring.
